//
// Implements a lightweight model for a 4G eNodeB or 5G gNodeB for generating
// configurable inter-cell interference in the simulated network.
//
// Compared to the ~eNodeB and ~gNodeB modules, this module occupies time-frequency
// resources in both the uplink and downlink bandwidth without simulating the actual
// transmission or reception of data packets to or from User Equipments (UEs).
// Therefore, it is significantly more efficient from a simulation speed perspective.
// To achieve this, it includes a ~BackgroundTrafficGenerator to customize the level of background
// traffic to be simulated, a ~BackgroundCellChannelModel to configure channel parameters, and a
// ~BackgroundScheduler that manages the allocation of time-frequency resources based on the traffic
// generator.
// Note that this module can generate interference on only one Component Carrier, as configured
// in the ~BackgroundScheduler module. To produce interference across multiple carriers, it is
// possible to use multiple instances of this module, each configured with the desired carrier frequency.
//
